Description

Technical Field

[0001] This utility model relates to a packaging component, specifically a padding component that is packaged at the end of an air conditioner indoor unit to provide cushioning and protection. Background Technology

[0002] From the time an air conditioner leaves the factory to its installation in the user's home, it undergoes packaging, handling, and transportation. During these processes, air conditioners are susceptible to drops, collisions, and vibrations, which may damage them or even affect their functionality. To protect air conditioners, cushioning is typically used for cushioning.

[0003] The indoor unit of an air conditioner is roughly rectangular in shape. Based on the orientation of the panel facing the unit, existing systems use two gaskets, one on each of the left and right ends. For example, patent CN 221189867 U discloses a packaging structure for an air conditioner indoor unit, including a packaging tube and two opposing support members. Both support members have receiving grooves whose shape conforms to the shape of the ends of the indoor unit. The receiving grooves wrap around the indoor unit from the sides, with the entire left and right ends of the indoor unit being wrapped by the two support members, and then fully enclosed by the packaging tube. The support members also have handle grooves to facilitate the operator to grasp or lift the indoor unit assembly from the outside.

[0004] The gaskets in air conditioner indoor units are made of lightweight material, typically EPS (polystyrene). To ensure sufficient cushioning and protection, the gaskets need to be thick enough to effectively absorb energy; they also require a well-designed vibration-damping structure to enhance vibration reduction. The gaskets must also possess sufficient strength to ensure structural stability and impact resistance, preventing collapse, cracking, or other damage to the indoor unit after impact. Currently, most existing air conditioner indoor unit gaskets are solid structures without proper vibration-damping features, resulting in thicker gaskets, higher material usage, and higher costs. Furthermore, these gaskets are generally discarded after use, leading to significant material waste. Utility Model Content

[0005] This utility model provides a buffer pad at the end of an air conditioner indoor unit, with the aim of improving the vibration damping performance of the pad and reducing the amount of material used.

[0006] The technical solution adopted by this utility model is as follows: the end buffer pad of the air conditioner indoor unit includes a rectangular base plate and four side plates located around the base plate. The four side plates are all rectangular and perpendicular to the base plate. The side plates and the base plate are integral. The overall shape of the base plate and the side plates is cuboid. The base plate and the four side plates form a cuboid and open inner cavity. Vibration damping holes are evenly arranged on the outer surface of the base plate. The vibration damping holes are blind holes. Vibration damping grooves are provided on the outer surface of the side plates. The vibration damping grooves are triangular. The base of the triangle is located on the side of the side plate away from the base plate. The two sides of the triangle are located on the side plate and intersect at the side plate. The connection part of two adjacent side plates is a solid structure.

[0007] Both the base plate and side plates are made of lightweight materials; specifically, both the base plate and side plates are made of EPS (expanded polystyrene).

[0008] To facilitate the fabrication of vibration damping holes on the base plate, the center line of the vibration damping hole is perpendicular to the plane corresponding to the base plate, and the projection of the vibration damping hole on the plane corresponding to the base plate does not overlap with the projection of the side plate.

[0009] To ensure the strength of the base plate, the base plate is further provided with oblong or waist-shaped holes at intervals along the center lines of both length and width. The four regions formed by the center lines of length and width are arranged with circular holes in rows and columns, and the diameters of the oblong and waist-shaped holes are smaller than the diameters of the circular holes.

[0010] The shape of the vibration damping groove is optimized, and furthermore, the triangle corresponding to the vibration damping groove is both an isosceles triangle and an acute triangle.

[0011] To ensure the strength of the external corner formed by the base plate and side plate in the event of a drop, the following further applies: the distance between the intersection of the two sides of the triangle corresponding to the vibration damping groove and the outer surface of the base plate is not less than 25mm.

[0012] In order to reduce the amount of material used in the side plate by using the vibration damping groove, specifically, the depth of the vibration damping groove should be greater than 10mm.

[0013] To ensure the strength of the side plate itself, specifically: the minimum distance between two adjacent damping grooves is greater than 25mm.

[0014] The beneficial effects of this utility model are as follows: The buffer pad at the end of the air conditioner indoor unit has good buffering and energy absorption effects as well as structural strength. While ensuring sufficient buffering protection, it saves material usage and reduces packaging costs. Vibration-damping holes are evenly distributed on the outer surface of the base plate, increasing the deformability of the base plate after impact and reducing material usage. The vibration-damping holes on the outer surface of the base plate are blind holes, meaning they do not penetrate the base plate, preventing excessive strength loss due to the installation of vibration-damping holes. The inner cavity formed by the base plate and the four side plates is used to house one end of the air conditioner indoor unit. Vibration-damping grooves are set on the outer surface of the side plates, preventing them from affecting the contact between the inner surface of the side plates and the air conditioner indoor unit. The corner formed by the base plate and the side plate is the most vulnerable to impact, as is the corner formed by two adjacent side plates. However, the side plates that are far from the base plate and the corner formed by two side plates are less vulnerable to impact. Vibration damping grooves are set on the outer surface of the side plates, and the shape and position of the vibration damping grooves are defined to prevent the vibration damping grooves from reducing the strength of the side plates in the impact-prone areas. At the same time, the amount of material used in the side plates is reduced, and the deformability of the side plates is increased. Attached Figure Description

[0016] Reference numerals: base plate 1, side plate 2, vibration damping hole 3, vibration damping groove 4. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] This utility model is used for installation at the end of an air conditioner indoor unit, wrapping around the end of the indoor unit to cushion impacts and protect it. Figure 1 and Figure 2As shown, the air conditioner indoor unit end buffer pad of this utility model includes a rectangular base plate 1 and four side plates 2 located around the base plate 1. Both the base plate 1 and the four side plates 2 are rectangular; that is, the base plate 1 is rectangular if its thickness is ignored, and each side plate 2 is rectangular if the thickness of each side plate 2 is ignored. All four side plates 2 are perpendicular to the base plate 1, and adjacent side plates 2 are perpendicular to each other. The overall shape of the base plate 1 and side plates 2 is cuboid, forming a cuboid-shaped, open inner cavity. This inner cavity is used to house one end of the air conditioner indoor unit; therefore, the shape of the inner cavity matches the shape of the end of the air conditioner indoor unit. The end of the air conditioner indoor unit is placed into the inner cavity, and the base plate 1 and the four side plates 2 enclose the end of the air conditioner indoor unit. The two adjacent side panels 2 and the base plate 1 and side panels 2 are all integral. The base plate 1 and side panels 2 are both made of lightweight materials, such as EPS material. The base plate 1 and the four side panels 2 are integrally formed.

[0019] Vibration damping holes 3 are evenly distributed on the outer surface of the base plate 1 to increase the deformability of the base plate 1 after impact and reduce the material usage of the base plate 1. The vibration damping holes 3 are blind holes, meaning they do not penetrate the base plate 1, preventing excessive strength loss due to the installation of the vibration damping holes 3. The vibration damping holes 3 should avoid locations on the base plate 1 that are easily impacted. The external angle formed by the base plate 1 and the side plate 2 is the most vulnerable location. To ensure the strength of the base plate 1, the projection of the vibration damping holes 3 on the plane corresponding to the base plate 1 does not overlap with the projection of the side plate 2; that is, the vibration damping holes 3 are not located at the edges of the base plate 1. To facilitate manufacturing, the vibration damping holes 3 are columnar, with their centerlines perpendicular to the plane corresponding to the base plate 1. The shape of the vibration damping holes 3 is the same on any cross-section parallel to the plane of the base plate 1. The cross-section of the vibration damping holes 3 parallel to the plane of the base plate 1 is generally circular, but other shapes such as ellipse, oblong, or waist-shaped are also possible. See [example example]. Figure 2 The base plate 1 has oblong or waist-shaped holes spaced apart along its length and width centerlines. Circular holes are arranged in rows and columns within four regions formed by the length and width centerlines, with the diameters of the oblong and waist-shaped holes being smaller than the diameters of the circular holes. The oblong, waist-shaped, and circular holes are all vibration damping holes 3. The diameter of the oblong hole refers to the distance between the two farthest points on the cross-section of the oblong hole; the diameter of the waist-shaped hole refers to the distance between the two farthest points on the cross-section of the waist-shaped hole.

[0020] The outer surface of the side plate 2 is provided with a vibration damping groove 4. The vibration damping groove 4 is triangular, with the base of the triangle located on the side of the side plate 2 away from the bottom plate 1, and the two sides of the triangle located on the side plate 2 and intersecting at the side plate 2. The vibration damping groove 4 is triangular, meaning that even ignoring the depth of the vibration damping groove 4, it is triangular in shape, with the depth direction of the vibration damping groove 4 consistent with the thickness direction of the side plate 2. The depth of the vibration damping groove 4 is consistent at different positions, therefore the vibration damping groove 4 is actually in the shape of a regular triangular prism. In order to effectively reduce the material usage of the side plate 2, the depth of the vibration damping groove 4 is generally greater than 10mm, for example, the depth of the vibration damping groove 4 is 13.7mm. The external angle formed by the base plate 1 and the side plate 2 is the most vulnerable to impact. The external angle formed by two adjacent side plates 2 is also susceptible to impact. However, the parts of the side plates 2 furthest from the base plate 1 and from the external angle formed by two adjacent side plates 2 are less vulnerable to impact. Therefore, the connection between adjacent side plates 2 is a solid structure, meaning that the connection between adjacent side plates 2 does not have a damping groove 4. Furthermore, the damping groove 4 is triangular, with the base of the triangle located on the side plate 2 furthest from the base plate 1, and the two sides of the triangle intersecting at the side plate 2. Placing the damping groove 4 in the less impact-prone areas of the side plate 2 avoids excessively reducing the strength of the side plate 2, reduces material usage, and increases the deformability of the side plate 2. Based on the impact force and deformation patterns of the damping groove 4, the triangle corresponding to the damping groove 4 is preferably both an isosceles triangle and an acute triangle, such as... Figure 1 and Figure 2 As shown. In order to ensure the strength of the external corner formed by the base plate 1 and the side plate 2 in the event of a drop, the distance from the intersection of the two sides of the triangle corresponding to the vibration damping groove 4 to the outer surface of the base plate 1 is not less than 25mm, for example, 41.5mm.

[0021] The number of vibration damping grooves 4 on the same side plate 2 can be one or more, depending on the dimensions of the side plate 2. When there are multiple vibration damping grooves 4 on the same side plate 2, the size and thickness of each groove 4 should preferably be the same, and they should be arranged at equal intervals. To ensure the strength of the side plate 2 itself, the minimum distance between two vibration damping grooves 4 needs to be controlled. For example, the minimum distance between two adjacent vibration damping grooves 4 should be greater than 25mm, or, for example, 29.3mm. The minimum distance between two adjacent vibration damping grooves 4 refers to the distance between the base sides of the triangles corresponding to the two adjacent vibration damping grooves 4.
